From KAVAN RC Wiki

Cover the wing panels with separate strips of tissue; attach the tissue to the rib, using a pencil and steel ruler or a piece of flexible plastic draw the line marking the joint of 6 and 18 ribs on the tissue. Trim the tissue to the line and glue it in place in the usual manner. You will have to cut the tissue in short 4-8 mm portions around the wing tip in order to follow the curve of the tip.
